Physicists have updated theoretical calculations of the muon g-2, and the new results now closely match the latest measurements, easing a 25-year discrepancy. However, the older calculations were based partly on experimental data and still appear valid, creating a new conflict that may point to issues in past measurements or to previously unseen physics.
